While most kids were playing stickball out in the street, Buffett was rubbing elbows with Wall Street's most powerful players.

"After lunch, a guy came along with a tray that had all these different kinds of tobacco leaves on it," Buffett recalled. "He made a cigar for Mr. Mol, who picked out the leaves he wanted. And I thought, this is it. It can't get any better than this. A custom-made cigar."

It was at that moment Buffett realized he would dedicate his life to making money.

Buffett caught the investing bug early. When he was 11 years old he purchased his first stock.

Buffett's hustle game was strong as a youth. While he was a high-school student he and a friend operated a lucrative pinball business.

"I bought this old pinball machine for 25 bucks, and we can have a partnership. Your part of the deal is to fix it up. And lookit, we'll tell Frank Erico, the barber, 'We represent Wilson's Coin-Operated Machine Company, and we have a proposition from Mr. Wilson. It's at no risk to you. Let's put this nickel machine in the back, Mr. Erico, and your customers can play while they wait. And we'll split the money."

The duo struck a deal with Erico and the machine was an immediate hit, raking in $4 bucks on the first night.

Rather than spending their earnings, the young partners reinvested it in more machines.

In a couple of months, Buffett was a pinball kingpin with several machines operating at barbershops across his town. Buffett sold the business for over $1,000 after a year.

In addition to the pinball business, Buffett undertook a number of odd business ventures during his childhood such as delivering newspapers, selling gum and soda, and washing cars.

Through his various business endeavors, Buffett amassed a small fortune of $53,000 (in today's money) by the time he was 16.

He enrolled at Columbia after he learned that the book's author, Ben Graham, was a professor there. Despite the fact that Buffett was the sole student to earn an A+ in one of Graham's classes, Graham refused to hire Buffett at his firm. He even advised Buffett to completely avoid a career on Wall Street.

As such, after he earned his master's degree in 1951, Buffett moved back and sold securities for Buffett-Falk & Co., his father's brokerage firm in Omaha, for three years.

Buffett got hitched in 1952.

Forbes

In 1952, while he was working for his father's company, Buffett married Susan "Susie" Thompson. The couple had three children: Susan, Howard, and Peter.

Things were not easy for the young couple right after their nuptials. They lived extremely modestly in a small three-room apartment, which they rented for $65 a month.

In 1957, Buffett purchased a five-bedroom home in Omaha for $31,500. He still lives there.

Mrs. Buffett left her husband when she was 45. She remained married, to Warren, but lived in San Francisco. The two remained close and spoke frequently on the phone and even went on vacations together. Ultimately it was Susie who set Warren up with Astrid Menks, a waitress who moved in with Buffett and then married him after Susie died.

Buffett moved back to the Big Apple.

Ultimately, Graham had a change of heart and in 1954 he offered Buffett a job in New York. So the family packed their bags and moved to the Big Apple.

Buffett worked for his mentor for two years as an analyst at Graham-Newman Corp., where he made the modern-day equivalent of $105,000 a year.

Buffett merged all his partnerships into one and invested in a textile-manufacturing firm, Berkshire Hathaway.

In 1962, Buffett decided to merge all of his partnerships into one and invested in a textile-manufacturing firm called Berkshire Hathaway. He started buying up shares of Berkshire Hathaway during the early 1960s and ultimately took complete control of the firm.

Buffett owned about 7% of Coca-Cola Co. by 1988. It ended up being one of his best investments.

"Buffett's [$1 billion investment] in Coca-Cola grew nearly 16 times over the ensuing 27 years when accounting for dividends. This is an annualized gain of 11%, approximately."

"He became the richest person in the world in 2008 with a total net worth estimated at $62 billion by Forbes, overtaking Bill Gates who had been the No.1 on Forbes list for the past 13 years. The very next year, Gates regained the first position and Buffett moved to second place."

In 2016, he beat his own personal philanthropic record by donating $2.86 billion worth of Berkshire Hathaway stock to numerous charities, including The Bill and Melinda Gates Foundation. That donation brought his lifetime givings to more than $28.5 billion.

In addition, Buffett and fellow billionaire Bill Gates agreed to donate at least half of their fortunes to charity when they created and signed the Giving Pledge.

Since 2010, over 150 people have made the pledge, including Facebook's Mark Zuckerberg.

Buffett was presented with the Presidential Medal of Freedom by President Obama in 2011.

The requirement of a sensible purchase price "proved a barrier to virtually all deals we reviewed in 2017, as prices for decent, but far from spectacular, businesses hit an all-time high. Indeed, price seemed almost irrelevant to an army of optimistic purchasers," he said.

Warren Buffett said in his recent annual letter to shareholders that the insurance business is "the engine that for 51 years has powered Berkshire's growth."

The business itself usually makes modest profits, but "the float" enables the company to make massive profits in investments.

The question is now: When will Buffett retire?

Abel was appointed as Berkshire's vice chairman for non-insurance business operations, and Jain as vice chairman, insurance operations. Buffett described the appointments as "part of a movement toward succession," providing the clearest hint of the pool of candidates he's considering to replace himself.
